Storing Star San

[meirion658]

Evening all I'm just about to passivate my SS brew bucket with 5 gallons of Star San solution.

Not wanting to waste it, can it be reused? What is the best type of container and how long will it keep for? Will temperature fluctuations affect it as well as I will be storing it in the Gardem shed.

Sorry for all the questions

I mix mine in a bucket on brew day (with a lid) , it tends to last quite a while and I have checked it with a pH meter 2 weeks later and it is still below 2.5 so all good. I tend to keep using it for jobs like bottling etc and remix only on Brewdays.
